Watch vids on RIO! All kidding aside, any of the 4 you listed (or all of them) are great ideas. I'm in the same boat right now, as I'm going to play my first EPT in Barcelona. I have played the WSOP ME before, and a few other higher buy ins, so I somewhat know what to expect though.

I'm not really sure how the Seminole will play, but as an overall, these types of buy ins tend to be quite a bit more about raising wars than the level you are normally playing. You will see lots of 3bets and 4 bets pre. I'd suggest watching some videos on defending vs 3b's and considering doing some range building exercises... take a while to really think about how your range functions on a variety of flops, and do your best to add/remove hands to allow you to continue on lots of flops. The tournament will play quite deep for a while, so remain patient.

Most importantly - have fun. Don't get down on yourself if you take some losses early, as the long levels and slow structure will leave you lots of time to recover. Get lots of rest, eat well and keep a level head. Best of it to you!

Yeah, have fun and if not comfortable doing all the european style 4-5-6 bet pre stuff take those guys to the streets as a certain jcarver tends to say ;) GG and GL
